I simply had an astonishing day !
The service is very complete. The guide came pick me up at my hotel in Usa River around 8am, and we entered the park around 9am. I got to see a lot of wild animals (girafes, baboons, zebras, buffalos,...) during the day, from far away and from up close. My guide even improvised a walk with a professional ranger in the park, so we got to approach animals such as warthogs, while still respecting the bush and the animals's way of life.
The employees really know the bush and the wild life, so they are able to explain lots of things (in English and in French please !).
I highly recommend this tour, if you seek an intimate yet beautiful experience with rather accessible fees
